Lotran is a planet in the centre system, only 5,678 lightyears from the central black hole. underground is a huge open space created where the IGF gather.
The planet is one of the most boring places in the universe, there is no life and the geography is actually the same a Mercury.
On the surface you only got the Malanian crater (see picture: almost in the middle). Undeground you got the IGF-room, although most times it is closed for the public every two Gaia years there is one Gaia week when it is open for the public.
