They are physically similar to a tree, a long central "trunk" with branches at either end with weapons and engine components on each branch.
They fire purple PEP blasts.
They are approximately twice the size of an Alexander-MkII starship.
Despite the fact they are in constant use and are greatly feared the ships are mroe often than not in various states of disrepair as the Nostluhk who know how to fix them have died and the Trict do not have the knowledge of hwo to fix them. As a result they are often dangerous to look at, but can be taken on by ships much smaller in size.
