Braxiatel Collection
The Braxiatel Collection was located on asteroid KS-159. Irving Braxiatel won KS-159 as part of a card game. He did so partly because he wished to investigate the Oracle of the Lost, but then decided to use it as a base for his collection. (BNA: Tears of the Oracle)
Braxiatel had been building a collection of many items prior to the destruction of Dellah. (BNA: Where Angels Fear) He had much of it in storage X One Nine in a series of large warehouses, one of which contained a secret apartment. He built gravity generators and set KS-159 up as the Braxiatel Collection. (BNA: Tears of the Oracle)
