Yeah, just give Valaena the egg.
Also,
@Diomedon, revised minor actions:
1. Have Lya Fabricate sets of Reinforced, Segmented Masterwork Mithral Fullplate for Tyene, Dany, and Vee, using 82.5 lbs of our Mithral and leaving 194 lbs in reserve.
2. Have the Veloc corpse processed for useful materials, magical reagents, and then mended and stuffed.
3. In her spare time, Lya should be Fabricating weapons and armor for our Legions, as steel becomes available.
4. Reva and Liset spend time near the Heart Trees and learn whatever magic Bloodraven tries to teach them.
5. Purchase Fine Maps of the following to pave the way for adventuring, exploring, and conquest: Giant World Map, Large Essos Map, Large Westeros Map, Tyrosh Map, Braavos Map, Myr Map, Pentos Map, Lorath Map, Qohor Map, Norvos Map, Volantis Map, Mantarys Map, Tolos Map, Ib Map, Rhoyne & Tributaries Map, Sothoryos Map, Summer Islands Map, Slaver's Bay Map, Astapor Map, Mereen Map, Yunkai Map, Basilisk Isles Map, North Map, Vale Map, Riverlands Map, Stormlands Map, Reach Map, Westerlands Map, Iron Islands Map, Dorne Map.
6. In the middle of the month, send Azema (with a greater disguise ribbon) and Aradia to root out and hunt down the devil worshipers on Greenstone.
7. Give Valaena her dragon egg and pass on the dragonlore advice you received.
8. Inform Rhaella who our human looking wards are and ask her help in keeping an eye on them.
9. Check in on our magical wards (Calapinas and Changeling babies)
10. Plant weirwood cuttings on every island you rule in the Stepstones aside from Sorcerer's Deep: Saltcliff, Westhaven, Deepcleft, and Port Sorrow. Also see if the men at He'Nekar have any objections to you planting a Weirwood Tree there.
11. Valaena, Argo, Bronn, Leila, etc (basically every baby adventurer available) goes on the Queen Rhaella to scout Daemon's Folly to purge any monsters or other things hiding there to clear it out as a future Legion fortress.
12. Equipping Subjects: PfE and Healing Belts for all baby adventurers as made available by Leila (dictated by crafting plan), Bronn gets the +1 mithral bastard sword once identified, a +1 adamantine dirk, and +1 armor of his preference. Argo +1 large fullplate from armory, +1 Razor-sharp greataxe commissioned from the smiths. Valaena receives the +1 blessed thinblade for now, and dragonhide armor and dragonbone bow for Soft Strider (made from Velroc).
13. Malarys tells us what he knows of Valyria, dragonlore, and magic.
14. We set aside gold to make a dragonpen for Malarys (and a dragonpen for Rhaella if she's ready for it).
15. Malarys writes a book on Valyrian Law as he knows it, to be added to our archives.
16. Viserys' dragonpen writes down all lore deemed safe to write down which we received from the Children of the Forest and Bloodraven.
