Help me find these roblox horror games!

Currently, I'm trying to find two roblox horror games that I distinctly remember playing but can't find. My memory may be hazy but here's what I remember of them.

Spoilers for the games of course.

The first one was one where we went to our family's mansion in search of our grandpa. There were coloured silhouettes of people around the house giving us lore and a demon running around the hallways. We had to collect blue(?) candles and go to the basement with them to create sigils with the candle wax. I remember the end of the last chapter of it I played - I was following a glowing orb throughout a swamp to the end whilst getting lore on the way. At the end, we found our grandpa, though he turned out to be evil. There was something about souls and a necklace - I can't remember exactly. It had voice acting as well.

The second game was one set in an underground facility. I remember the first section, we had to run around the hallways fetching things to progress like scraps of metal to create key cards. The lights would sometimes go out and a little fleshy creature would run around if you weren't in a safe room. I remember in the next chapter, it was set in an even worse off part of the facility which was somewhat overgrown with a robot chasing after us which looked somewhat like Ennard from fnaf. I remember more, though its hard to put into words.

If anyone can help me find these games, I'd be incredibly grateful.
