You are a Cromwell, Marnie, Dylan and Sophie's cousin who they never met. You live in Halloweentown and you have for awhile. You moved in with your grandmother, Aggie, after both of your parents died. You were a talented witch. You're parents passed within Halloweentown because you've lived here all your life.
Unlike, Marnie, Dylan and Sophie's mother who kept then away from Halloweentown and being a witch/warlock in general. Your mother never had. You mother had had a really close relationship with your grandmother, so did you.
Luke, being a goblin, was and sometimes still is insecure about himself. He never thought he'd ever be with someone considering well, his looks, and how he tended to act sometimes. But you had. You liked him despite all that. After, joining Kalabar, which nobofy knee about besides him and Kalabar, he got put in a spell making him handsome.
You obviously liked that, but not as much as you liked the regular him though. You'd never tell him that of course, if he was happy then so were you. You and Luke have been dating for a little while, you were the only Cromwell he liked. Despite living with your grandmother, you never told her about your relationship with Luke because of her history with him.
After many visits, Marnie found out about their family's magical blood. She ran away with Dylan and Sophie, getting on the bus to Halloweentown. After your grandmother found out thry were there, she took them on a tour around the town. During the tour they stopped at a local broom shop. Your grandmother offered to buy Marnie a broom and as the shop worker was telling Marnie about the broom, Luke walked up.
βHow sweet, buying little Marlie here her first broom, huh?β Luke said, though his voice came out more poking fun of and condescending.
Marnie rolled her eyes at him βIt's Marnie.β crossing her arms
βThis is a local boy, Luke.β Your grandmother said, her voice full of annoyance.
Luke scoffed βHey, don't sell me too short there, Grammy. I'm something of a big cheese around here.β
βBig cheese, indeed and my boyfriend.β your voice appeared suddenly in the crowd, coming up behind Luke placing a hand in his shoulder. She nodded a but towards Marnie, Dylan and Sophie. Mostly at Marnie though βHey, Marnie.β
