Etrian Odyssey Untold: The Millennium Girl/Gladsheim AREA I

After you arrive the soldier will give you 3 Medica and a Nectar. You can speak to the soldier again to rest. Begin exploring the area. At D2 is a locked door and a small crevice opposite of it. Go through the crevice and touch the switch inside. This will unlock the door. Another animated cutscene will play where a girl comes out of a capsule. Three others join you as a monster attacks.

Boss: Errant Camel
The Errant Camel is weak to elemental attacks so use any of the Young Boy's formulas as the main attack. The Redhead should use Front Guard and Provoke to reduce physical damage and the Doctor should heal up anyone low on HP. Use Odd Girl's Head Snipe to bind the Errant Camel's head and prevent it from using Hammerhead. After a few turns, the Errant Camel should be defeated.

Once the battle is over, talk to the trio and the girl. They will introduce themselves and join you in exploring the ruin. Check the device that Frederica awoke from. Continue on to each marked destination. After the last one, return to the entrance and speak to the soldier to return to Etria. Go to the Radha Hall and report the results of Investigate the abnomality.

After a conversation, you can create and name your guild. You will also receive Radha Note which you can take to Shilleka's Goods. Raquna suggests going to the pub and you can accept the following quests there.
 * The leathersmith's favor
 * A certain shop's request
 * To taste it once more...
 * Request from the inn I

When you are ready go to the Forest Entrance and continue exploring the labyrinth. Another cutscene will play. Go to the stairs and proceed to B2F
