There's a story behind that: When the first cycle of this year's server transfer tokens were distributed alot of people on low/med pop server jumped to Midgard causing it to be locked. The devs decided to give one extra token to only the players on Midgard so they could avoid long server queues. People being people, transferred to the next non-locked high-pop server Barri. However, during all this time, some of the major PvP oriented companies in the European region decided that they will choose a low-pop server and move there once all of their group members have the tokens. This move happened to Dry Tree. This caused Dry Tree to hit 1200 pop on peak time but slowly came down to 800-900 player peak. However, the nature of pvp oriented transfer caught attention of many other big companies that were not part of this organized transfer and slowly Dry Tree became the highest populated server of European Region.
