Is Thena from Asgard?

Could you please clarify for me if Thena, the character we're discussing, is indeed from the realm of Asgard as depicted in Norse mythology? I'm curious to know if her origins align with the traditional tales of the gods and goddesses residing in that mystical realm. Is there any evidence or context within the story or source material that specifically indicates her connection to Asgard? I'm eager to understand the details surrounding her background and origins.
