How to absorb matter and transform it to energy

I'm writing the last issue of my comic and I'm in trouble. My villain is a member of a cosmic cult that wants to absorb everything in the universe to create a conceptual/energy pangea out of space and time. In other words, the big boss is part of the universe itself and is trying to collapse the rest into himself to return to a pre-big bang state. To conquer planets and citizens the cult send a member to "plant" an obelisk that will absorb matter around itself and convert it to pure energy. Now, the question:

Presuming that the cult has every kind of power, how would the absorb process take place? In a movie, I would make the matter simply disappear but in a comic, I need something different, so I'm asking you how the process could happen in a pseudo-scientific way. Then I'll think about how to draw it.

PS: I'm lurking a lot and that's my first question, I'm kinda excited, you're an awesome community!

EDIT 1

I did not explained it well because it is very long and complex, also metaphorical. It's a kind of "need to be one together" again with the universe, but that's not the point. The obelisk will absorb the matter around itself, collapsing it into the big boss through the energy/mental connection that he has with the obelisk itself. I need a visual explanation more than a scientific one. I know how the physics works in my universe, I don't know how to conceptualize it onto drawings, so I asked for a scientific suggestion that would help me to visualize the process.
