Traveling on horseback is...an experience. We had been on the road for three days now, having departed from the Rustlands on horseback. I had never ridden a horse before, and the first few hours were pretty uncomfortable, but I managed to get the hang of it before long. Whenever we ran into monsters, we used Store to keep the horses safe, and Extract to bring them back after we took care of the monsters.
That spell preserves and maintains whatever it stores in the exact same state, including something alive...I had tried it out on bandits as well, and it worked. In other words, this spell had accidentally and unintentionally invented something similar to cryogenic preservation.
