Keltham wakes up more muzzily than the previous day, to dawn's light coming through his windows. It seems less like a design flaw if clerics have to pray for their spells during the dawn hour.
All right. Let's do this.
Keltham reviews his notes from the previous night, written appropriately cryptically, and then prays, trying to cast his mind Beyond, maybe in the direction that wasn't the three space or time, looking toward his deity: the Lawful Neutral god of people wanting to follow the protocols they must follow in order for their interactions to be mutually beneficial, come to the Pareto frontier, coordinate without vast enforcement costs, summing to powerful societies and markets even when people largely pursue their own individual interests individually, because they never step on others in order to do that.
Requests, obviously subject to amendation should his unknown god deem there to be better spells he could get:
0th: Detect Magic, Guidance
1st: Comprehend Languages, Truthspell, keep Sanctuary
2nd: Owl's Wisdom, Early Judgment
3rd: Invisibility Purge actually, how about his god only reassigns him Invisibility Purge, or Glimpse of Beyond, if Keltham still might need it
3rd: Owl's Wisdom
4th: Early Judgment
And also:
If conditional spell assignment works at all for communication with his god, please assign Read Weather (1st).
If the communication doesn't cost much, please assign Lighten Object (1st).
If the communication seems like it should be error-free and reliable, please assign Air Bubble (1st).
If Keltham should speak freely and teach as much as he can to his hosts, please assign Light (0th).
If Keltham should instead stall them with relatively less dangerous material, please assign Create Water (0th).
And if Keltham should run the ass out of here today with just Carissa and tell nobody else where he's going, please assign Lay of the Land (2nd).
Any remaining slots should be assigned as his god sees fit.
...Keltham would also like to talk, if now is a better time than yesterday, for whatever reason. Keltham has many questions about how he can best cooperate in a mutually beneficial way with his god.
