I checked up on the various members of Du Mintai (who doesn't like a good mystery?) and found this out:
Solemnus is still on Phoenix Throne (Remember he had to retire due to RL just before the transfers, so who knows what server he'll be autotransferred to.)
Magdalynn (28 WP?) is on Badlands.
Helore (40 AM) is on Badlands.
Alcewyn (31 AM) is on Badlands.
Lililira (16 SW?) is still on PT.
Thronbor (23 Slayer?) is still on PT. (There's a 40 Eng on Dark Crag by the same name.)
Now granted they may have had to change their names, but it looks like three of Du Mintai have transferred to Badlands. Depending on who the guild leader was, we could help them make their guild for the them.
