Candlelight

Candlelight, also known as The Pious Pete random is a discontinued random event. In it, the player was teleported to a chapel with a strange monk wandering around. The player had to talk to the monk, Pious Pete, and ask him what was wrong. Pious Pete responded that his candles always go out when he lit them, so he needed the player's help to light them. He would then give the player a lighter.

Once the player had the lighter, Pete told the player to light only the candles that are left standing, not the ones that are burnt down (he'd take care of those). There would be a screen with arrows to the left and the right, and a button in the middle. One pressed, the player would light the candle (if it was an unlit candle). After all the candles were lit, the player would talk to Pious Pete and be teleported back to where they were with a small reward. This event was likely the rarest, as very few players had ever gotten it. It is unknown when it was discontinued.

Miscellaneous
The random event's former location can be seen using the Orb of Oculus. If you go to the north section of the Blast Furnace minigame and look northeast, you can see that it is also west of the Gravedigger event. It is also northwest of Eagles' Peak and northeast of Mort Myre Swamp.
