What was that? Do I know from where the Rift Sprite Messengers came?
I am afraid that remains unclear to us. Some of our soldiers came into rather close contact with them during combat.
Perhaps they observed something that may help to answer your question.
I would start with Dharma and Bristol. You willl find them recovering from battle at the Ironwheel Outpost.
Once you have finished with your inquiries, please proceed to the Gullwing Lighthouse and report to Rescue Team Leader Browney the condition of the soldiers. Her knowledge of first aid has been invaluable to us.
