During the Riftwar, Tomas was accepted as the new warleader due to his extraordinary powers.
When the war erupted, they were joined by Tomas and the dwarves of the Grey Towers. For six years they held the boundaries of the forests as Tomas grew into Ashen-Shugar, and fell in love with his Mother-Queen.
Once, Macros approached Aglaranna and warned them about the Tsurani invasion the next day. Tathar trusted him as he had been a friend of his father (and Aglaranna's) before she could remember. Macros also told her about the fate of Tomas, that although the power of the Valheru could be disastrous and consume even himself, the Spellweavers (as well as his love for her) do help his humanity to preserve in the transformation.
The other day Macros aided the defense of the elves and dwarves against the Tsurani and the Cho-ja. At first he summoned all the birds of the forests against the invaders and then he killed from distance the four Great Ones who accompanied them. Eventually the battle was won and Macros left. After the battle, Aglaranna admitted her feelings to Tomas and took him as her lover, thereby losing her power to command him.
Tomas underwent a great change, bringing the forces of the Valheru and the human into balance. In a titanic inner battle, the human was nearly overcome, but at the end he mastered the raging inside him that was once the Dragon Lord and at last discovered peace within his soul. He became Prince-Consort to Aglaranna
After the Riftwar, Aglaranna announced to Thomas that she is pregnant to Calis.
