Canadian artist Jeffufu is a Guild War 2 fan. Recently he created some fine works relating to Guild Wars 2.
There are some stories behind each painting, just as what he described one of the paintings:
Every year in Tyria when Halloween comes around, the younger golems work themselves into a frenzy preparing costumes for the special holiday. Some dress up as mighty warriors and some... the complete opposite. Nonetheless, they can be found thumping about at night, carrying overflowing bags of candy, oblivious to the fact that they lack the means to consume them.
