Mithra Pride is the oldest English language linkshell in the known universe.
Deep background: Mithra Pride originated in FFXI's American beta. At its peak it had LSs (prides) on over half of the FFXI servers. It was always a social and helping LS wherever it was. In FFXI it was limited to Mithra. We have always welcomed role players, but that isn't a requirement.
We have a linkshell and Free Company on Sargatanas and are actively recruiting new members. The FC is mostly social, end game runs happen but there is no set scedule or atendance requirement.
For FFXIV we removed the strict racial limits. (Hey, there are no Mithra in XIV anyway, right?) Its still friendly and helpful but now anyone may join. Warning, we have a LOT of Miqo'te. (You do like kitties, don't you?) A few RPers too.
