Interstellar Diplomatic Mission

Create a detailed science fiction scenario where I am the lead diplomat on humanity's first official mission to establish relations with a newly discovered alien civilization. Develop a unique alien species with consistent biology, psychology, social structures, and values that differ significantly from human norms. The simulation should focus on cultural misunderstandings, communication challenges, and ethical dilemmas as we negotiate trade, scientific exchange, and territorial boundaries. Present complex diplomatic scenarios requiring me to balance Earth's interests with respect for alien perspectives. The scenario should be scientifically plausible and psychologically nuanced, avoiding common sci-fi tropes while exploring genuine questions of cross-species understanding.
