|Holotome Profile: Casterwill Library|
|Inhabitants|| Dellix |
|First Appearance||Memory Lane|
The place had been first discovered by Sophie and Cherit, when Dante sent them to look for a Foundation Library while he and Lok went to Mausoleum of Sir Lancelot. As they entered they had been observed by Lane and Dellix. Inside they found the key to a Casterwill cypher.
Later the whole team returned there to look for information about Willblade. It was then when they first encountered Lucas and his teammates. The two teams fought before coming to an understanding.
The library was also one of Sophie's recurring childhood memories.
- Lane mentions that the front door will only open for a Casterwill. However, the barrier will allow non-Casterwills to enter, so long as said condition is fulfilled.
