It sounds like you’re wanting to take a night’s rest before you investigate Hallod. That’s fine. Some of you have some conditions that need to be addressed. Wounded is easy. Restore HP with Treat Wounds, or be restored to full HP and rest for 10 minutes. Silvi’s Drained is going to be harder. Boy, they made stirges hella bad this edition! Drained will be reduced by 1 every night she gets a good rest (so a week to completely eliminate it). In the meantime, her HP value is reduced to 12. (13 in the morning, but you don’t automatically get that 1 hp back.). A night’s rest will restore your Con modifier x level in hit points. If you wish, you can take all day and night tomorrow to rest as well, to get Con mod x twice your level in hit points back.
Let me know what you would wish to do. Your "ticking clock" is a month, so you aren't really under any time pressure, to be fair. If you wanted to take the entire week off for Silvi, we could switch into Downtime Mode before you continue the investigation,. etc.
