Not a really hard quest, if level 46 or lower might want to take a friend at least 1t 46 or above. Most of the combatants are around 46 and 47 trolls deeper down are elite so need more in group or higher levels for that. Just to get a relic you do not. In fact can probably get outside main gates or the cave entrance into. From Thorin's Gate you travel down the road and take the second road to the right that leads you up and into the goblin camp, go all the way up the stairs and hill till you reach the dwarfs outside the cave entrance. The cave itself is just a little further from where you encounter them and a little to your left you basically walk into the wall.....
As to Asgeir himself, well if you got the quest and forgot where he is, he is inside the Blue Stone Garrison within Thorin's Hall.Behind the statue you take the first left, pass the stairs to right leading down into the tunnels just after turn right and continue around then across the bridge and there you find the superior crafting hall within aka The Blue Stone Garrison you will find Asgeir at the very back on your left.
I had to beg for help to find him, looked all over the halls but not within the superior crafting hall....felt so dumb. It had just been too long to remember and no hints or clues online to where he is.
