The Forgotten Server identifies itself as a fork of the OpenTibia Server project. Surviving OTLand threads document public TFS builds and version discussion in June and July 2007. Those records support a 2007 public origin while avoiding an unsupported exact day for the first private or test build.

The current GitHub repository was created on July 1, 2013, after years of SVN-era and distribution-era development. Its first published GitHub release is TFS 1.0 from November 1, 2014. The project therefore has an older community history than its current repository creation date.

Evidence classification: Forum and release-backed. The date shown in the reference box is phrased to match what the surviving source actually proves.

Early TFS distributions bundled an engine, datapack, map, XML configuration, Lua scripts, and database schema for a particular Tibia protocol. The 0.2, 0.3, and 0.4 families developed their own long-lived communities, and many later servers were forks or downgrades of those branches.

The 1.x era emphasized modern C++, CMake and package tooling, Lua APIs, safer memory management, Docker or CI support, clearer releases, and newer protocol work. Branch identity remains critical: a script written for 0.4 or a downgraded 1.2 tree cannot be assumed compatible with current master or a 1.4-based distribution.

TFS provides the authoritative game simulation: login and protocol handling, creatures, combat, movement, items, containers, houses, parties, guilds, conditions, scheduling, persistence, and the bridge between C++ engine code and Lua gameplay scripts.

Server developers use its Lua interfaces for actions, movements, creaturescripts, globalevents, talkactions, spells, weapons, NPCs, raids, quests, and custom systems. Database schemas, map files, OTB item mappings, client assets, and AAC websites complete the operating stack.

A disciplined deployment pins a TFS branch and commit, uses the matching schema and config, compiles with documented dependencies, imports only compatible datapack content, runs migrations, and validates gameplay on staging before accepting public accounts.

TFS is notable because it became both an engine and a vocabulary. Server advertisements routinely identify a TFS version, script authors target TFS Lua APIs, AAC projects publish compatibility tables, and map/item tooling is tested against TFS-derived contracts.

The release history also captures protocol preservation. The 1.4 release line is explicitly documented as the stable 10.98 family, while newer development extends engine and protocol behavior. This lets older-client communities and modern-client projects coexist without pretending they use the same runtime.

Confirm the exact branch, commit, protocol, database schema, compiler, dependency set, map format, OTB, Lua API, datapack origin, and client. Version labels copied by a fork may not reflect the actual source ancestry.

Review configuration defaults and security before exposing the server. Database credentials, RSA keys, admin accounts, web endpoints, ports, file permissions, crash handling, backups, and update procedures are production concerns, not optional installation details.

This page separates a confirmed public date from an assumed development date. Its release statement is: Earliest verified public TFS threads: June-July 2007.
