I need a brand identity for a holding company which owns and manage many other companies which are working in many sectors, such as tech, civil aviation, airports management systems, secure identity solutions, touristic projects and hotel management, power projects, oil and gas, logistics, telecommunications, and other investments projects

each company of the owned companies will have an identical name of the holding company with different extensions, for example: Xyria Capital Tech, Xyria Capital Consultancy, Xyria Capital Investments...etc

the X should be played and designed in a tricky way to be read as S.

Logo Variations are also needed for the sub companies which works in different domains
