Just an update for those interested:
Welp! After doing some prison prep, I found out that all my players were actually able to make it after all. So after a short scramble, I pulled together a largely improvised session that didn't end with the party going to prison.
They actually managed to get out of the heavily guarded tower, despite having just killed a powerful noble, mainly due to a highly-successful Calm Emotions spell and some clever bluffs.
They escaped the city and are now being pursued through the Underdark.
[MENTION=15921]Motorskills[/MENTION] - Thanks for directing me to Out of the Abyss. While I didn't get to run any of the prison material in there , the rest of the module is super helpful for general Underdark exploration. The party is currently about to enter the Silken Paths from section two...
