While leaving the Planetarium, on the right, you can talk to the Concerned Monk [M5.6], who asks you to find his brother. Along your path, you also run into Captain, who asks you to kill Deserters (as your proof, you need Human Tattoos). Along your path to the exit, you will also meet two talking knights [M5.7] (if you use the Blood Flint t set on fire the stack, as a result of which reinforcements arrived. Talking to them will earn you 500 EXP).

While standing in front of it, simply fire the gauntlet at the door..

Head towards the main exit (the big gate, you can open it by firing the gauntlet at it), behind which, there is a surprise for you.

As soon as the Beast's yellow bar disappears, land as many blows as you can.

Due to the size of the opponent fighting the Beast is a bit different from a standard battle. First of all, remain vigilant, because the boss's attacks deal an awful lot of damage (especially the club attack). Note that the opponent, apart from the health bar, also has a yellow one. If you land regular attack at his feet, you deal a rather scanty amount of damage but, this charges the yellow bar. As soon as the bar fills up and disappears temporarily, the boss kneels for a moment, which leaves him defenseless. This is the moment at which you should strike with strong blows - for a moment, the damage that you deal will be higher, and it is this way that you should drain the Beast's health bar. Land the strikes, which charge the yellow bar, mainly when the boss ends his charge and after the jumping attacks, at the moment at which he raises the club above his head. As for defense, it is necessary that you keep moving, at all times, and do not let the boss approach you too much and hit you. Also, dodge whenever the Beast jumps to hit you. Later into the battle, make sure that you do not step into the poison goo. All in all, keep circling around the boss and attack mainly after his charge, and after the jumping sword attack. As soon as the yellow bar fills up, land several strong blows at the opponent's back, because it is this way that you deal most of the damage.

The knight tells you about the mission that you now need to perform.

After the battle, talk to the knight, collect the to the right of the main entrance Planetarium Element [M2.20].

Note: At this point, you can either go to the Temple (the portal at the Cemetery), to follow the main storyline, or remain at the Citadel and in Keystone, in order to explore some more and complete side missions.
