idk if you've looked into it or not but isleofavalon has a pretty strong fate/ cast. i play the beowulf there and wouldn't mind seeing more fgo peeps. if you haven't looked into it this month's test drive is here. apps are closing tonight though.

otherwise i also play an ibaraki at noctium, diamondogs, which sets more of a futuristic tone to it. The latest TDM for it is from last month here. There should be another one popping up here in about a week or two for this month though. Apps are also currently closed for the month.
