Where altars can be placed
Altars are placed inside designated **claim zones** the game world reserves for player housing. The official map (the community map source) tags these as **Safe Land** (PvE-tagged plots — 168 plots ingested) and **Dangerous Land** (PvP-tagged plots — 61 plots ingested). The two-zone split is intentional: a Safe Land plot is the default home for PvE-server players, while a Dangerous Land plot exposes your altar to attack but unlocks the larger XP buff stack documented below. The in-game tooltip (localization string 1225) describes the area as "you can build an individual altar or a clan altar and start constructing your own buildings… players cannot damage your buildings in this area" — that wording applies to Safe Land. Dangerous Land plots have no such damage immunity, and altars there can be destroyed by attackers (string 2762: "Personal Altar is Under Attack!").
Personal vs Clan altar — one of each
Quinfall enforces a hard cap of **one personal altar per player** (localization string 707) and **one clan altar per clan** (string 706). The two are independent buffs and stack — see /xp for the multiplicative formula. Building a clan altar requires guild membership (string 708). Each altar tracks its own experience pool: "Individual Altar Experience" (string 715) and "Clan Altar Experience" (string 716) accrue from professions and building activity within the altar radius.
Blue vs Red bonus magnitudes
For **profession XP** the altar tier system is QA-confirmed: blue altar = +10% (×1.10), red altar = +110% (×2.10) per the 2026-05-02 QA correction (AngstyAmerican / Wolves at War). The /xp planner exposes both as tier selectors (none / blue / red) for personal and clan altars independently and stacks them multiplicatively. For **character XP** the only number currently documented is the +30% PvP-zone altar buff. A separate blue/red split for character XP is **not yet documented** — needs QA confirmation in-game.
Base-building — what altars unlock
The altar is the anchor for a player base. Once placed, the surrounding plot becomes buildable: workbenches, beds (string 1254 "Re-Spawn in the my nearest bed (Altar)"), storage chests, decorative furniture (string 2571: carpentry furniture grants comfort points in altar areas), and farming/animal husbandry (string 1550, 1553 — tame animals and plant seeds in the altar area). The buildable area scales with altar level (string 1783: "The building area grows according to the level. The higher the level, the higher the limit for the same type of workbench"). Altars themselves earn XP and level up (strings 714 / 1781).
Decay and upkeep
Altars decay if not maintained. When you remove or fail to fuel an altar, "all the objects on this altar begin to decay" (string 1651, 1787) and disappear after a fixed period. Items lost in PvP attacks are stored in an Altar Treasure / lost-items chest for **72 hours** before being permanently destroyed (string 1790). On a Dangerous Land plot, if attackers destroy the altar itself, they gain access to the chest contents.
Permissions & clan controls
Clan altars expose a permissions panel (strings 1636–1638): "Control the altar (except remove)", "Building/destroying structures on altar land", and "Interact with all builds under altar control". Disbanding a clan deletes the clan altar and all attached structures (string 1151) — a one-way operation.
