	You need the original Morrowind data files. If you haven't

	installation wizard which is the officially supported method
	(either by using the launcher or by calling 'openmw-wizard'

		USE flag 'qt5' is disabled, 'openmw-launcher' and

		making the Morrowind data files available and pointing
		openmw at them.\n\n
		Additionally; you must import the Morrowind.ini file before
		running openmw with the Morrowind data files for the first
		time. Typically this can be done like so:\n\n
		\t mkdir -p ~/.config/openmw\n
		\t openmw-iniimporter /path/to/Morrowind.ini ~/.config/openmw/openmw.cfg"
