Skalyre would be in the capital, cursing himself out on his way home. He had forgot the key to his house when leaving the house, and was already halfway to his destination, the hungry wolf tavern.
Once he reached his house, he walked in the small alley where his door was located, then up the 2 stairs he had to take. When he tried to open the door, however, he found that either it was jammed, or the lock fell closed when he left his home earlier.

"Work you.. Damn piece of.. Furniture"

He said as he tugged at the handle, realizing that using his strength wouldn't work. He then kneeled in front of the door and took out his knife, slowly sliding it into the lock and trying to use it as a sort of key, just turning it left and right repeatedly, in hopes that the lock would somehow unjam itself, occasionally tugging the handle, hoping the door would open.

*Arcturus would be walking through the city square. A warden in the Shield Guardians, he was a more experienced knight, and had spent much time in Alynthi. His normal routes lead him through the square almost weekly, and as such he has left his horse back in the stables, enjoying the good old fashioned walk. His sword would be sheathed at his side, available to be drawn but not threatening currently. 

As he continues on his patrol, he'd spot a Tiefling working on a door with what appeared to be a knife. Almost like... Lockpicking. "Another Tiefling thief" He'd think, approaching the Tielfing, hand on hilt.*

"Citizen, everything alright?"

Skalyre jumped up slightly upon hearing the sound of the Aasimar knight that had approached him. The knife would still be jammed into the lock, slowly sliding out and dropping on the floor a few seconds later.
He looked at it drop, before looking back at the knight.

"I.. Look, I uhh I know this looks.. Ehm weird, but I can explain it"

He said as he used his tail to slide the knife closer to hkmself, intending to pick it up and sheathe it in his belt.
What didn't help was his red skin and eyes, paired with the black clothes and the small tusks portruding his chin he looked like a textbook villain.

*Arcturus' right hand would be resting on his hilt, able to be drawn instantly if the situation escalated. Even with his training as a Knight, he was still aware to the fact not everyone was a criminal. Deciding to first analyze the evidence in his head before making a verdict. To begin, they are both located in the city square. This is a high traffic location with tons of indiviuals moving through constantly. For an individual to commit a crime here would be rather easy if they did it right, and at the right time. This may have been the case if Arcturus hadn't decided to walk through at this time today. As well, the individual in front of him is in black clothes, and even though his instincts tell him otherwise, for the moment he is ignoring the race of the subject. He appears to have been attempting to break into this home, but he wasn't quiet nor quick about it. While he technically had enough evidence to at least detain or search the Tiefling, he'd choose to not start our on the wrong foot with this individual.* 
"Please, endugle me. Why are you attempting to break into this home that would make me believe this is a legal matter, and not a violation punishable by jail time."
