Well, I know that OS and I were mentioning in an rp (or was it me hinting) of Luke doing something (studying, reforming the Jedi?, etc..) with the restored Jedi Temple on the Commonwealth world of Elrood.
However, at the same time, I had heard that Irtar (that's Gro to all you newbies) was going to factor Luke heavily in an rp so I may not have gone into detail much with Luke in favor of Irtar's idea.. but if Irtar never got his idea off the ground (ie: rp'd), then he would/could possibly still be tinkering around the Jedi Temple on Elrood.
The Commonwealth world of Elrood is famous (in Caprician eyes anyway) [and is probably a little recognized fact] as the only planet (or one of the few) with both a Sith Temple and a Jedi Temple. The Jedi Temple was built by Jedi Artimir (back in the days when we were at TGC) and the Sith Temple was built by the Marzullo Clan when Itala captured Elrood and Artimir (also back in TGC days).
That is why there is a heavy Commonwealth educational investment/presence there.
