Preliminary plan. I think we should go to Eastwatch first, for reasons I outlined a few pages back. We can ferry all of the Children, except for maybe one who wishes to see the giants, back to SD with Rhaella, rest up, then return to Eastwatch before heading for Castle Black.
[X] Together, Viserys, Dany, and Richard will explain the past eight years in broad strokes, so as to not overwhelm Rhaella more than absolutely necessary. Do not lie, or try to obfuscate the truth, but save the deeper, more disturbing truths for later, once she's back in Sorcerer's Deep, an unfamiliar place, but at least one that fits within her mental paradigm.
-[X] Once Dany has a chance to prepare her spells, she will swap out Blessed Aim for another Endure Elements spell for Rhaella and Revivify for Greater Stone Shape. If we are forced to make camp for a night North of the Wall, she will use Greater Stone Shape to create a small, fortified redoubt from the nearest acceptable rock outcropping. Later, we will share the location of this fort with the Brothers of the Nightwatch so that they may use it in the future.
--[X] When we are ready to depart, give Bloodraven our farewells and heartfelt thanks for returning our mother to us and sharing such important information with us. Express our regret that the obsidian sand will not allow us to remain in regular contact with him.
---[X] Viserys will create 13 Phantom Steeds for everyone to ride; eight using all of his 3rd level spell slots, two using four 2nd level spell slots, and three using 4th level spell slots. Two Children of the Forest will need to ride on most of the steeds. We will then ride for Castle Black at the best possible speed, flying low enough to avoid the harshest of the Northern winds, but high enough to be safe from random attacks made by ground-based threats.
