Today Torax wandered outside the Lombard Desert and got killed by Ythril.
I killed Ythril to avenge him, got the Tectonic Bulwark then proceed to clear the library in the desert but Torax's Wildland remained, forever... Wildland.
End of Primal_Savage's quote
Oh, God, Torax.
In my current game, I cleared the early part, but realized I couldn't beat Torax himself (yet) and since it was a cul-de-sac, I left. So he pouted in the far back corner for half an age, until I was just about ready and sent in a scout who stayed at maximum range, moving forward one square a turn.
Not only did Torax wake up and have his surviving minions chase down and munch the scout (I stopped too soon when I thought I was safe), but my main army only just caught up to him a couple turns later as he was about to leave the wildland entirely. One more turn and I might not have been able to get credit.
