Drak'Tharon is a PVP Central Timezone server founded on November 18th 2008 shortly after the release of WotLK. The server was opened up for free transfers from a large assortment of overpopulated realms with the goal of population dispersal.
The server's name comes from Drak'Tharon Keep located between Grizzly Hills and Zul'Drak.
Drak'Tharon was a low population realm until Blizzard opened up free transfers again on January 7th 2009. Within a few days after free transfers opened to Drak'Tharon once again, the realm was sitting at a locked state. Transfers were closed shortly after.
With high latency all around and constant server queues, Drak'Tharon was given free transfers off the realm on January 27th 2009.  This brought Drak'Tharon down to a medium population realm and all has been good since.
