The Claw's base

"The Claw"s Base is a big castle not too far from Inwirn's Second Base. It was built by the Matoran Hunters for "The Claw". "The Claw" spent all his time in his castle after it was done.

When "The Claw" found the badly damaged Alex, he took him to the base.

In the final battle of Return of the Enemies, a part of the castle was destroyed, along with a big indoor bridge, leading from a room to another. After this the base was abandoned, only Inwirn visiting it afterwards.
