Upon reaching the Last Light Inn, you are instructed to find Jaheira about the plans to come, which involve you first being blessed by a cleric named Isobel.
You head to the second floor of the inn to meet Isobel, who bestows the Blessing of Selune onto your party to give you protection from the darkness.
This event is interrupted by the arrival of a man named Marcus, who has been sent by the absolute to kidnap Isobel, the only person keeping the Last Light Inn safe from the darkness.
How To Stop Isobel’s Abduction?
To stop Isobel from being abducted, you will need to defeat Flaming Fist Marcus and the Winged Horrors as their goal is to take her back alive at all costs.
Isobel must not be defeated, or this will trigger a cutscene where she is carried off by Marcus, where she will be taken to the Moonrise Towers.
This requires that you fight Marcus and the Winged Horrors while keeping Isobel safe until you have defeated all the enemies in the area.
What Happens If Isobel is Kidnapped?
If Isobel is taken by Marcus, the spell the protection that she had been providing the Last Light Inn will fade, allowing the darkness to enter.
All of those within the Last Light Inn will succumb to the darkness and you will end up having to kill them as they will now be undead.
Isobel being taken away will cause the Last Light Inn to no longer be safe, pushing you on a path to Moonrise Towers without a place to fall back to.
How To Defeat Flaming Fist Marcus?
Flaming Fist Marcus has a decent amount of health, which includes temporary Hit Points, and as the fight continues, Winged Horrors will move towards your location.
You will need to damage Marcus as much as you can and eliminate the Winged Horrors before they can swarm Isobel. (They will be focusing on her more than on your partner)
It would be a good idea to knock Marcus back if you have attacks that can do this and heal/buff Isobel to keep her from taking too much damage.
Focus on defeating the enemy’s order based on who is closest to Isobel to allow her to help you and keep her from losing her health.
Once all of the enemies have been defeated, Isobel will be safe and the Last Light Inn will persevere, giving you a place to rest and trade.
Blessing of Selune
During your conversation with Isobel, she will provide you and your party with the Blessing of Selune, which will keep you safe from most of the dangers in the Shadow-Cursed Lands.
This however does not protect you from everything as the deeper areas have stronger darkness amongst them, which requires more protection.
Regardless of whether Isobel is taken by Marcus, the Blessing of Selune will remain, giving you a better chance to reach the Moonrise towers.
Verdict
Preventing Isobel from being taken can be a vital part of the game as this will determine the fate of the Last Light Inn.
The Last Light Inn is the safest place from the darkness and a good place to rest up and trade while you are preparing to head for Moonrise Towers.
Isobel will fight back during the invasion, which makes it vital to consider protecting her and creating space between her and the enemies that you encounter.
