Diplomatic action
"I, Ultmar of House Vathyra, with a heart overflowing in gratitude, do hearby declare that the valiant champions of the mighty Erudas shall henceforth be honored as the 'Dwarvos Nor,' brothers of our sacred hearth and home, bound in noble alliance." -Ultmar Vathyra, 1088 c.e.
After receiving aid from the Dwarves and witnessing their might in battle, the Elves meet with the Dwarves to propose an alliance. Knowing that they could finish the war with the combined strength of the Elves and the Dwarves, they agree.
