I also have Valindra Shadowmantle for my sorc PvP alt.
I just think the legacy system is the niftyest thing ever put into an MMO, it's so awesome and I cannot give Bioware enough kudos for thinking about it. Now if only the servers were not 40 minutes late coming back online! =(
I completely forgot that if you choose to display your surname as a title it adds in the Legacy part, for some reason I thought it just threw a The onto your surname. So I choose Darkstar,after one of my favorite characters nicknames from the ASoIF books, thinking I could display it as Temeluchus The Darkstar.
Didn't work out that way and Lord Temeluchus Darkstar still works, might have to rename an alt or two because the surname doesn't match their first names or just toggle it off for them.
I chose Nih'lathak because I like the way it sounds and is an obvious lift from the Diablo 2 character.
I chose Opress because I am Zabrak and the Opress name is Zabrak (Maul, Feral, Savage) so I like to think I am their ancient Sith Marauder ancestor.
My legacy name is Stormbinder. The character I'm playing currently is based off of Storm from Marvel comics so she is named Ororo. I felt very cleaver doing this, didn't want her last name from the comics, since the character wears white shooting lighting. But I don't think anyone gets it. :/
