Convince the admiral to take you into the battle | Chapter V Memoria Guide

1 - laboratory's left window, 2 - laboratory's right window, 3 - an observatory, 4 - a council's room, 5 - a roof, 6 - the guest room, 7 - a main hall

While being outside, look at the windows - you can get to the ore laboratory (by using left or right window), to the observatory, onto the roof, to the guestroom, to the main hall and to the council's room (???). In the first place fly to the laboratory by using the left window.

Take a water kettle, put it on the stove and quickly leave the room by using the same window.

Now fly to the laboratory by using the right window, quickly take your dagger and leave the room by using the same window.

This time fly to the observatory. Here you can find three horns. Click on the first of them and then on the sphere, which is above the horn. Then do the same with other horns and spheres. Sadja will overhear a conversation and thanks to it you will gain the twenty-third achievement. Leave the observatory.

Lastly, go to the council hall (???). Talk with the admiral. After the cut scene talk again with the admiral and give to him the dagger.
