Seven Signs - Contract of Mammon

Talk to Sir Gustav Athebaldt in the Town of Oren again. He will tell you the legend of the Seven Seals, as well as the need to gain control of the existing contract that Emperor Shunaiman entered into with the merchants of Mammon. Watch a video about this.
Talk to Sir Gustav Athebaldt again and agree to his offer. It will be necessary to penetrate the Secret Oracle - a very dangerous place. He will tell you about Secret Agent Kollin . You can find the agent at the southern exit from Aden Square.
Head to Town of Aden and take the southern exit from the square. Talk to Collin. The training consists of 3 stages. At the first stage, Agent Colleen will turn you into a frog.
In the form of a frog, you need to come to Narsell Lake, to the place where the “Forest of Mirrors” teleport leads from Aden, talk there with the Frog Prince Great King Frog and get the family jewel from him. It is impossible to use Portal Guardians in the form of a frog, so you will have to move on your own. However, the frog has the "Frog Jump" skill, which increases speed by 15 seconds for

33. With its help you can get there faster - this is necessary, because the duration of the transformation is only 10 minutes.
Upon arrival at the place, you will see the Frog Prince - Great King Frog - next to the teleport point. Talk to him and he will give you the Jewel of the Frog Prince.
To remove the transformation, jump into Lake Narsill, and in normal form return to Aden, to Agent Collin.
Talk to agent Kollin, he will take the Jewel of the Frog Prince from you, and you will proceed to the second stage of the training. At this stage, Agent Colleen will turn you into a child (a male character will become a boy, and a female character will become a girl), you will need to run in this form to Grandma Tess and bring the gift you received from her. The Portal guardians still do not pay attention to you, so again you need to move on your own two feet. The child also has an acceleration skill - Run, which increases speed by 15 seconds by 33 - this is necessary because the duration of the transformation is only 7 minutes.
Run to The Forest of Mirrors and find Granny Tez there. Talk to her and she will give you Grandma Tess' Candy Pouch (Granny Tez's Sweets).
To remove the transformation effect, dive into the nearest body of water, then return to Agent Collin in Aden.
Talk to Agent Collin, he will take Granny Tez's Sweets from you, and you will proceed to the third and final stage of the training. At this stage, Agent Colleen will turn you into an Aborigine. In this form, you will need to go to the Coliseum, talk to Native Kuta there, and bring Collin a gift from him. The Guardians of the Portal do not consider aborigines to be people, so we still move on foot, fortunately, the aborigine has the “Turn” skill, which is similar in stats to the accelerating skills of a child and a frog - this is necessary, because the duration of the transformation is only 3 minutes...
Run to the western entrance to the Colosseum and talk to the Aborigine Kuda there. He will give you gloves.
Take a dip in the nearby body of water to remove the transformation, and return to Aden to Agent Collin.
Talk to Agent Collin, he will take the Kuda Aborigine gloves from you, inform you that the training was successful, and send you to Claudia Athebalt. She stands outside the northern gate of Aden, a little forward and to the right.
Talk to Claudia Atebalth. The quest is completed.
