Veitendur

Could you clarify what "veitendur" refers to? It may be a common Icelandic term (for example, a plural noun meaning "experts" or "knowledge bearers") or the name of a specific organization, publication, group, or work. Providing the intended meaning, domain (linguistics, culture, history, current usage, etc.), and any sources or context would help me draft a neutral, concise wiki-style article under 300 words.
