Si'Nat takes a look. "Well, three of them I can't read, but the fourth one is a Read Magic scroll.... I'm guessing it'll help read the others."
Which is true, magic-users and elves have to cast Read Magic on magic scrolls to use them. Cleric scrolls are in Common and can be read by anyone, but only clerics can use them. Other types of scrolls can generally be read by anyone such as protection scrolls and treasure maps, although some treasure maps must be read with a Read Languages spell.
The Read Magic spell has been added to Si'Nat's spellbook
