After choosing a Race you would like to be ascended from, you will have to complete the quest which the Race Master asks you.
When you've completed the quest, bring all the requirements to the Master and then, he will ask you to proceed to Etheria, the God of Afterlife to complete your ascension.
Etheria will then reborn you to Novice High and will give you an Accessory which will be the source of you new powers.
Remember that when you reborn as a Novice High, you will still transcend into your original Class.
