To get information about age limits, you'll need to:
* Specify what "House of Night" you're referring to: If you are talking about a specific production, tell me the name of the show, the location, and any other relevant information.
* Check the official website or contact the organizers: The official website or contact information for the production should have details about the age limits for auditions.
For example, if you're interested in auditioning for a local theatre production of "House of Night," search for the theatre's website or contact them directly.
If you're thinking about a fictional scenario, you can create your own rules about age limits.
Let me know if you have more information about the "House of Night" you are referring to, and I'll do my best to help you find the information you need.
