NeroRuins

The ruins arrive: six structure families, puzzles, guardians, vaults, relics and expedition tools. Requires Neroland Core 1.17.4. This is a beta: everything below is built and covered by automated tests, but most structures have not yet been played through in a survival world. Please report anything that breaks.

Added

• Six ruin families, each a hub with seeded satellite structures, so layouts, room choices and outlying pieces differ between worlds but stay the same for a given seed. Apart from the Earth bunker, they generate in Nerospace's worlds, so install Nerospace to find them (the Halcyon Ark also appears in vanilla void worlds):
  • Survey Bunker — a hatch-and-ladder shelter on every world, and rarely on Earth's dry land (roughly one every 1–1.5 km).
  • Lattice Temple — the Architects' precincts. The Lattice Citadel on Nyxara descends two spiral wells to a sanctum about 86 blocks below its plaza; complexes on Nyxara and Cindara, wayshrines everywhere.
  • Halcyon Ark — the Survey's broken generation ship drifting in the station's void, with a severed hull section on Luna.
  • Survey Lab — a research complex that goes down: twelve floors under Mars, smaller labs on Greenxertz and Glacira, and outposts everywhere.
  • Colony Field — a lost colony's sprawl, with its citadel on Glacira and a complex on Greenxertz.
  • Crash Site — the half-buried freighter Meridian on Cindara with a debris field, and wrecks on every moon and planet.
• Puzzles, all solvable from clues in the room and randomised per ruin: Ballast Plates (weight), glyph sequences with a keypad screen, conduit routing, resonance tuning, three keycard tiers with card readers, and relic sockets that hand the relic back. Sealed Doors open when a nearby puzzle is solved.
• Guardians: the Sentinel in three marks, with melee and a charged arc shot that never damages blocks; the Ruin Spawner, which wakes for nearby players and has a limited budget; and the Arc Grate floor trap. Spawn lists are data-driven and include NeroCreatures mobs when that mod is installed.
• Vault caches that roll their loot per player. A roll that does not fit in your inventory is held for you and delivered exactly when you return. Vaults behind a puzzle stay sealed until it is solved; with first_come vault mode the solver's roll is reserved.
• Protected gated rooms: every room behind a puzzle gate is enclosed in reinforced, unbreakable and blast-proof hull or lattice, so gates cannot be bypassed by mining. Shells outside gates stay mineable.
• Loot tiers 0–4 with nine named relics (one per chapter). Each relic grants a small passive while held; the Surveyor's Compass points to your nearest unexplored ruin. Sibling-mod items join the loot only when those mods are installed.
• Expedition Record, Expedition Map and Survey Scanner. The map lists the ruins you have entered; the scanner gives the direction and rough distance of the nearest ruin, never coordinates.
• Data logs placed through the structures in story order, readable from terminals and shards, collected in the Codex.
• Expedition Notes quests (NeroQuests, optional): 29 quests that walk you through the release — the first bunker and log, Sentinels, vaults, puzzles, keycards and relics, finding each ruin family, finishing each Codex chapter, and server milestones for claiming each citadel's vault. Completing a Codex chapter now opens a progression gate other mods and quest packs can use.
• Blocks: Lattice palette (Latticework, Lattice Floor, Resonance Crystal Block, sixteen Glyph Stones), puzzle fixtures, reinforced variants, and a facing Log Terminal.
• Commands for operators: /neroruins gallery [family] builds a showcase of the mod's blocks, items, Sentinels and structure pieces, and /neroruins bench <structure> [samples] measures generation cost.
• /neroruins privacy export now also lists held vault rewards and your Expedition Record.

Changed

• Now requires Neroland Core 1.17.4 or later, which reports incomplete player-data erasure.
• Survey Bunker hubs sit deeper, so rooms on slopes stay buried and the hatch still reaches the surface.
• The Codex checks client support before sending its screen payload and explains when the client cannot receive it.

Privacy

• New personal data (held vault rewards, the Expedition Record) is included in export and in Core's erasure. Expedition positions are dropped after privacy.expeditionRetentionDays.

Not yet included

• Most structures have not been walked end to end in survival; generation cost is measured and within budget.
• Per-world decay for most families, NeroAgriculture planters in colony farms, named cemetery markers, an Ark cryopod block, uses for the Reach Thermal Core and Rootglass Vessel, an admin placement command, the NeroLink link module and companion-app pages, and push notifications.
• The guardians.enabled, traps.enabled, privacy.archiveRetention and pushNotifications.enabled settings are reserved and have no effect yet.
