1. What Is the Everspire?¶

The Everspire is a colossal, ancient tower-like structure that descends deep beneath the surface of Atherion.
It is the primary endgame pillar of the game and the most consistent source of long-term progression.

In-world, the Everspire is:

unstable
partially unexplored
constantly changing
dangerous even for veteran adventurers

From a systems perspective, the Everspire is:

instanced
repeatable
scalable
designed for longevity rather than one-time completion

The Everspire exists not to be “finished,” but to be engaged with over the lifetime of the game.

2. Why the Everspire Exists (Design Purpose)¶

Decision (hard):
Everspire is the core PvE progression structure, not optional side content.

Rationale:
Many MMOs struggle with:

endgame fragmentation
open-world zerg dependency
constant replacement of old content

Everspire addresses this by:

providing a single, expandable progression spine
allowing new content to be layered vertically instead of replaced
supporting both solo and group play without splitting player populations

New expansions extend or reinterpret the Everspire, rather than discarding it.

3. Structural Overview¶

3.1. Floors, Depths, and Layers¶

The Everspire is composed of:

Floors – individual playable segments
Depth bands – ranges of floors with shared themes/mechanics
Special layers – unique encounters, hubs, or anomalies

Example (illustrative only):

Floors 1–20: Shattered Ruins
Floors 21–40: Elemental Faults
Floors 41–60: Forgotten Sanctums
Floors 61+: Unknown / evolving content

This structure allows:

thematic consistency
mechanical escalation
selective refresh of older layers

Exact numbers are intentionally left flexible.

3.2. Procedural vs Curated Content¶

Decision (exploratory):
Everspire floors are likely a hybrid of procedural generation and curated encounters.

Rationale:

Fully procedural content risks feeling disposable.
Fully curated content risks exhaustion and content burn.

Working assumption:

Layouts, enemy packs, and modifiers may be procedural.
Bosses, key events, and story moments are curated.
Some floors are fixed “anchors” for progression milestones.

This balance can shift over time.

4. Entry, Access, and Instancing¶

4.1. Entry Model¶

Decision (current):
Everspire is accessed via instanced runs.

Solo players may enter alone.
Groups enter as parties (and potentially larger formations later).
Entry is intentional, not accidental (no open-world walk-in).

Rationale:
This ensures:

predictable simulation load
controlled difficulty
fair progression tracking
resilience against griefing or zerg dominance

4.2. Instance Lifecycle¶

Each Everspire run:

is created on entry
has a clear ownership (party or solo)
runs at higher simulation fidelity than open world
is destroyed on completion or abandonment

Runs may be:

short (a few floors)
extended (multi-floor expeditions)
challenge-oriented (specific conditions)

Persistence beyond a single session is an open question.

5. Difficulty, Risk, and Failure¶

5.1. Risk Is Real¶

Decision (current):
Failure in the Everspire has meaningful consequences, but is not excessively punitive.

Possible consequences (illustrative):

loss of progress within the run
durability or resource loss
forfeiting certain rewards

What failure should not cause:

permanent character loss
loss of long-term progression
discouragement from retrying

5.2. Scaling Difficulty¶

Difficulty scales through:

enemy behavior complexity
environmental hazards
resource pressure
limited recovery opportunities

Rather than:

raw stat inflation
arbitrary damage spikes

This supports skill expression and team coordination.

6. Solo vs Group Play¶

Decision (directional):
Everspire supports both solo and group play, but not equally at all depths.

Rationale:

Solo players need meaningful progression paths.
Group play enables deeper mechanics and social cohesion.

Working assumptions:

Early and mid-depth floors are solo-viable.
Deeper or special floors strongly encourage grouping.
Some content is explicitly designed for coordinated teams.

Solo players are not blocked from the Everspire, but peak challenges are social by design.

7. Rewards and Progression¶

7.1. What the Everspire Provides¶

The Everspire is a primary source of:

rare materials
unique modifiers or effects
blueprints and crafting knowledge
adventurer rank progression
narrative discoveries

It is not the sole source of everything, but it is the most consistent.

7.2. Power Philosophy¶

Decision (aligned with Vision):
Everspire rewards emphasize:

access
options
specialization

Not:

runaway numerical superiority

Examples:

unlocking new crafting possibilities
enabling alternate builds
earning recognition for high-rank content completion

This keeps older content relevant and reduces power invalidation.

The Everspire interacts heavily with:

crafting professions (materials, blueprints)
companies (coordinated runs, shared goals)
the adventurer guild (rank, recognition)

It is intentionally not isolated content.

Success in the Everspire should:

ripple outward into the economy
strengthen social structures
create reasons for cooperation

9. Relationship to Live Operations¶

Decision (hard constraint):
Everspire must be compatible with no forced maintenance downtime.

Implications:

runs must be drainable
patch epochs must allow existing runs to finish
disconnect/reconnect must be survivable
extreme failures must be compensatable

This influences both design and technical architecture.

10. Open Questions¶

These are intentionally left unresolved:

Should Everspire runs persist across sessions?
How many floors is a “standard” run?
How much randomness is too much?
Should certain floors be globally shared events?
How visible are Everspire achievements to other players?

These will be refined through prototyping and testing.

11. Relationship to Other Documents¶

This document feeds into:

gameplay/core-loop.md
gameplay/progression-adventurer-rank.md
technical-design/architecture.md
technical-design/backend/instance-model.md

Any system affecting long-term progression must be evaluated against Everspire’s role as the core pillar.
