Tâchan is a frozen area on the edge of the Regadnîn wastes. An 800 square mile area of deep blue ice, Tâchan seals a rift to the Sea of Entropy. In the Creation War (1486 DE - 8777 DE), the Golden Seven and a captured primordial entombed the rift and its Entropy Arch, along with hundreds of fire archons.
In the Second Battle of Regadnîn, we captured Thyrm. After a lengthy interrogation by Ares and Ditherra, Thyrm revealed the location of an Entropy Arch in the wastes of Regadnîn. We traveled with Thyrm to the gateway, sealing it with his ice magic.
Thyrm's magic created the frozen wastes of Tâchan. It is an ice that does not melt and is impervious to fire. Its presence plays havoc with the weather, giving rise to foggy conditions and sometimes bone-numbing cold with a temperature range of -10 to -60 degrees.
