Raelorasz wants you to use Raelorasz' flare at the Nexus' northwest entrance.
1x Assault on Malygos Complete
We owe this opportunity in great part to your efforts, [player].
It is only fitting that you initiate the attack on Malygos.
Take this flare and use it just outside the northwest entrance to the Nexus. Keristrasza will join you there.
