mikillvæg

Could you clarify what you mean by "mikillvæg"? It could refer to different things, and I want to make sure I write the article accurately:

- If mikillvæg is a common Icelandic word or form, I can create a concise linguistic/etymology-focused entry explaining its meaning, usage, and how it relates to related words like mikilvægi.

- If mikillvæg is the name of a person, organization, band, work, or brand, I can draft a wiki-style article about that entity, including any notable facts, history, and context.

Please specify which interpretation you’d like, or provide any other context you have.
