In The Elder Scrolls IV: Oblivion, you can join multiple guilds simultaneously. Specifically, you can be a member of all five major guilds at the same time without having to choose just one or two. These five main guild factions are:
- Fighters Guild
- Mages Guild
- Thieves Guild
- Dark Brotherhood
- Arena
You can join each of these guilds and progress through their respective questlines independently
. In Oblivion Remastered, this remains true as well-you can join multiple guilds at once and enjoy the benefits and quests from each faction simultaneously. However, each guild has its own rules, and violating them (such as harming guildmates in the Dark Brotherhood) can result in expulsion
. Therefore, the maximum number of guilds you can join in Oblivion is five, corresponding to the five main guild factions available in the game. Some sources mention other factions and groups, but the core guilds you can join and actively participate in are these five
