Welcome to Verulia!
As the TDS or Town Defense Squad, you will high likely be on a lot of “Go there and kill the big mean baddie” missions. Chances are you may have to team up with the hunters and gradualy grow stronger, and hopefully take their places.
In here you may find who all are in the Squad as we speak.
When you’re loaded with spare time, feel free to read upon their latest adventures!
After that, take a look at your wiki. There is some more helpful info there.
