I think the triangular bucklers fit very well and would/could be quite effective (and they fit the khadorian motif), I’ve done some sparring with sword and bucklers and they are very nasty in the right hands. The larger banner I sent to you is from the Dark Elf Cold One Knights sprue (in case you want to find another) as it had similar angular motifs to the shields.
Do you have any deals regarding colour scheme yet or will the sludge cover most of the poor souls?
