Astrid is one of the members of the Twilight Sages. She is a member of the Arde House and protects the future of humanity by protecting the Chaos Dream in the Dream Realm and therefore keeping the Savior asleep.
She has the dreamwalker bloodline and has many spirits as her subordinates. Margaret is one of the spirits and it is responsible for having countermeasures in case Astrid's life ever comes in danger. For this reason, Roel believes that Astrid may actually still be alive at this point in time.
Later, it is revealed that Astrid has fused with the Chaos Dream. The Twilight Sages Assembly was against waking her to prevent the risk of stopping the Chaos Dream from functioning.
To wake her up, there are two items required:
- The Blackrose Ring that contains Astrid's Dream Realm.
- A possessor of a similar bloodline. Antonio says that the key to find a possessor of the dreamwalker bloodline has to do with the Knight Kingdom Pendor.
